extreme cases, the rot can be so severe that the skin, flesh and core of the fruit breaks down completely and proceeds to leak of out the shell surrounding once healthy fruit. When infection occurs out in the field, brown lesions can develop in wet weather where leaves rub together in the wind. In dry weather, white, paper spots with margins develop. Plants are usually stunted, produce an unusual foul odor, show a soft base rot of the stem and young leaves, and drop their fruit prematurely.

triazole fungicide such as triadimenol and/or propiconazole and maintain refrigeration at 9 °C which limits the sporulation of conidia. When packing up the fruit and getting ready for transportation, it is important to maintain strict hygiene to avoid unwanted infection between fruits. When trying to minimize transmission of the disease out in the field, it is recommended to improve soil drainage to avoid excess moisture and, therefore, not to plant during wet weather.

present, chlamydospores are found in the soil and plant debris of previously infected plants. Pieces of pineapple are planted the following growing season to grow new pineapple. The pieces of pineapple fruit farmers use, however, may contain chlamydospores and, therefore, transmit the disease to the next generation of plants.

Pineapples are grown all around the world and, as a result, pineapple black rot is a widespread disease. They are grown mainly in Asia, Africa, North, South and Central America, the Caribbean, and Europe but also in Australia, Fiji, French Polynesia, New Caledonia, Papua New Guinea, Samoa, Solomon

There are several ways to minimize the effects and transmission of pineapple black rot. If the fruit is already infected, placing it in a hot water bath of a minimum of 50 °C can help minimize the post-harvest symptoms. It is also recommended, if you are storing the infected fruit, to is in a

Fruit that is bruised and/or damage and is kept in unsanitary and high humidity conditions are especially susceptible to this disease. Once infected, the fruit begins to form brown/black lesions. Over time, the lesions become soft, water rot spots making the fruit unappetizing and inedible. In
